A UK-based tech news site pointed out on Monday that the Zollkriminalamt (Customs Investigation Bureau) is looking (Google Translate) for two new developers to work on the latest version of the state-sponsored spyware. The trojan reportedly could make VoIP calls, record keystrokes, capture screenshots, and more—all as part of government investigations.

The two-year job requires at least three years of experience in IT and telecom, with “technical knowledge in IT security architectures.” German media reported last year that the malware has been used “over 50 times” as part of criminal investigations.

However, the German government said just last month (Google Translate) that the older version, which was purchased from a German software company, was no longer in use by federal authorities. The job ad appears to be part of the government’s efforts to develop new spyware in-house.

Still, many including Germany’s justice minister, Sabine Leutheusser-Schnarrenberger, have pointed out—covert software stored on government computers can be a target for hacking itself.

“There is a very real possibility of a significant disaster,” she told Der Spiegel last year. “A third party logs on to a computer via a Trojan horse that investigators have installed and proceeds to misuse the data or even change it. Such an eventuality has to make investigators uneasy as well. The interior minister has to take such a possibility seriously too.”
